Care instructions: Regular machine washing, warm (temperatures up to 40 degrees ) with mild detergent. Wash microfiber cloths separately from other laundry or in a laundry bag, as the fine structure of microfiber, attracts lint and dust. Spin lightly. Never use bleach or fabric softener (gums up thin fibers, limits function of microfiber cloth). Do not iron. We recommend air drying and if dryer, only a few minutes and low temperatures.
